Radeon HD 6750 1GB vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which features a clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X will be 13% quicker than the Radeon HD 6750 1GB in general, because of its greater bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 6750 1GB		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X will be quite a bit (more or less 23%) more effective at AF than the Radeon HD 6750 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 5900 (23%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M370X is the winner, but only just. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 1200 (10%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
